CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 349,655, datedseptember 21, 1886.

Application filed July .17, 1886,

Serial No. $109,236. (No model.)

To all whom it may concern.-

Be it known that I, ISAAC KLING, of Louisville, in the county of Jeftcrson and State of to the letters of reference marked thereon, which form part ot'this specification,in which Figure 1 is a vertical longitudinal sect-ion of thedraw-bar of a car and coupling device com-;

plete. Figs. 2, 3, 4, 5,6, 7, and 8 are detail of the various parts of the coupler.

This invention relates to implovements inautomatic car-couplers of the loose-pinand- ]ink variety; and it consists in the hereinafterdescribed construction and arrangement of parts pointed out in the appended claims,and readily understood upon reference to the illustrations in the accompanying drawings, formingpart of this specification.

ignates a hollow draw-bar of ordinary construction, having the flaring draw -head A, The interior of the draw-head converges from its mouth to the outer end of the recess or hollow of the draw-bar, which recess is rectangular in cross-section, about two and one-half or threeinchesin diameter,aud extends nearly to the rear end of the draw-bar, as shown.

F is a bolt entering a proper opening in the inner end of the draw-bar, and retained in place by the tapered key E, that passes into proper slots in the draw-bar and said bolt. The said bolt is adapted to engage in a suitable opening in a front transverse iron bar on the car-truck, the key G passing through a suitable opening in the bolt in rear of said,

iron bar, and aiding in securing the former to the latter.

(1 is a pin of ordinary construction, which passes into the openings W and H in the upper and lower surfaces, respectively, of the draw-bar, and retains the link B inplace. y is the head of said pin, by which it may be lifted to release the link and uncouple the draw-bars.

R is a block of general rectangular shape, situated in the recess of the draw-bar near the inner end of the link. The outer end of said block is bifurcated, and is provided with a point of the pin 0 and prevent its descent.-

-When the link B, however, enters the drawhead, it impinges against the swinging block,

drives the point V inward and upward, and allows the pin to descend and retain the link in the draw-head.

T is a concave part of the front edge of the block U, against which part the end of the link strikes, and is thereby prevented from sliding under the lower edgeof said block and wed g- Referring by letter to the drawings, A desing it in the draw-bar. This concave part of the frontedge also serves to keep the link horizontal, so that'its' outer end will enter the opposite draw-head at right angles to the outer end thereof.

- Q. is a hook on the lower part of the inner end of the block R. The said hook looks upward and has a convex or rounded face at its point,and immediately above its shank, in the end of the block R, is a recess, q, for a purpose hereinafter explained? I is along block of general rectangular shape bearing against the bottom of tlie recess of the draw-bar and deeply bifurcated at its outer end, so as to form the arms W, parallel and rectangular in cross-section.

i is a longitudinal groove in the upper sur face of the body of the block I, and J is a key or wedge for insertion in said groove. The wedge J has on its under surface the wedgeshaped projections j j, which rest in corresponding recesses in the floor of the groove i, so that the wedge and block I can be inserted together in the recess or draw-bar.

. j is a transverse opening through the wedge, near the heel of the same. This opening is for the purpose of drawing the wedge outward and unbinding the block I. To bind the said block in place a rod is inserted through the mouth of the draw-head and the wedge J is driven inward, so that its projections j ride upward and inward 011 their recesses. To unbind the block ahook-rod is similarlyinserted, its point engaged in the opening j and the wedge drawn outward. The block I can then be removed from the draw-bar, with the-wedge resting upon it. The block I. can be thus fixed in place in the recess of the draw-bar, the wedge binding against the roof of the recess.

L is a coil-spring, the inner end of which is secured to or in the body of the block I between the arms WV, its outer end bearing against the inner end of the shank of a hook, N, from which. a\pin, M, extends inward and is surrounded by the coil-spring, so as to support thesame. The point of the hook N looks downward, being adapted to engage with the hook Q on the block R. The two hooks do not bind on eachother tightly, and when engaged the point of the hook N enters the recess q, to prevent it disengaging from the hook Q.

I is a longitudinal slot running from side to side through the body of the hook N, and O is a transverse pin passing through said slot and having its ends secured to the arms W of the block I. It is evident that when the link has struck and turned upward the block U the block R will be pressed inward, and will. press inward the hook N against the action of the spring L, so that no break age, caused by jar, will take place in coupling. The pressing back of the block R also gives more clearance for the fall of the pin. Should the hooks become accidentally uncoupled, the pressing back of the block It will cause the hook N to ride over and engage the hook Q, and the recess (1 will hold them engaged, as explained.

K is a disengaging-bar for the hook N. The said bar has its lower end pivoted to the shank of. the hook Q in a recess in the side of said shank, and is provided with the inclined shoulder 7c, flush with the upper surface thereof, so that the point of the hook N rests partially on said shoulder. The upper end of the bar K rests against the inner end of a groove, 1), made in the upper surface of the arms of the block R.

Z is a disengagingrod with ahandle on its end outside of the draw-head, and its inner end resting against the bar K. hen the rod is pushed inward,it turns said bar on its pivot, and by means of the shoulder It raises the hook N from the hook Q. The block I and wedge J can then be removed, as described.

Having described my invention, I claim as new 1. The combination, with the recessed drawbar, the link entering the draw-head, and the pin, of the sliding bifurcated block in the recess of the draw-bar, provided with the downwardly-looking shoulder between the arms of its bifurcation, the swinging block pivoted between the arms of the sliding block, provided with the upwardly-looking shoulder on its inner edge to engage the shoulder on the sliding block, and the extended front outer corner to fall forward and downward and support the end of the pin,so as to prevent the same from falling, and devices,substantially as described, in the recess of the draw-bar, to bear against the sliding block and prevent breakage by jar in coupling.

2. The combination, with the recessed drawbar and the sliding block. situated in the recess thereof, and having on its inner end the upwardly looking hook, of the long bifurcated block I, having a longitudinal recessed groove in its upper surface, the wedge lying in said groove having the projections j, to fit in the recesses therein, and binding the block I .in the recess of the drawbar, the coiled spring secured to or in said block I, between the arms thereof, and the slotted downwardlylooking hook attached to the block I, between the armsthereof, by means of a pin passing through its slot and engaging the upwardlylooking hook on the sliding bifurcated block, substantially as specified.

3. The combination, with the link and pin, of the herein described coupler-head, composedof the recessed draw-bar A, having the flaring draw-head A, the bifurcated block R, provided with the shoulder X, hook Q, and recess q, the pivoted block U, provided with the shoulder S and point V, the bifurcated block I, provided with the recessed groove 23 and arms W, the wedge J, having the projections] and opening j, spring L, pin 0, and hook N, provided with the slot 1?, and pin M, all constructed and arranged substantially as and for the purpose specified.

4. The combination,with the recessed drawhead, bifurcated block I, and hook N, connected thereto, of the sliding block R, hook Q, firmly secured thereto or forming part thereof, the disengaging-bar pivoted to the hook Q, and the disengaging rod Z, moving in the groove P of the sliding block, substantially as specified.

5. The combination, in a carcoupler, of the downwardly-looking hook N, connected with a block,I, in the recess of the draw-head, near the bottom of the same, the upwardlylooking hook Q, provided in the side of its shank with the recess q, the disengaging-bar K, having its lower end pivoted in the recess q, and provided with the shoulder 70, and the disengaging-rod Z, moving in the groove 1) of the block It, substantially as specified.

In testimony that Iclaim the foregoing as my own I affix my signature in presence of two witnesses.

ISAAC KLING.
